AT1731 Overview
The AT1731 is a PWM DC/DC converter control IC with 2 channel outputs that can directly drive power MOSFET. This IC ia suitable for very small DC/DC converters because of their small and thin package(1.1 mm max.), and high operation frequency (up to 1.0 MHz).
AT1731 Key Features
- Low input voltage: 2.5V to 7V
- 2-Channels PWM Control: 1 Boost Controller(CH1) 1 Inverting Controller (CH2)
- Adjustable Soft start time and maximum duty cycle
- Built-in timer latch for short circuit protection: Delay time=216/(Switching frequency)
- Built-in under-voltage lockout, thermal shutdown
- High operating frequency: 100kHz to 1MHz
